UNITED STATES DEMPSEY C. BRIT'ION, OF CONNERSVILLE, INDIANA.

RADIATOR.

Application filed July 16, 1924. Serial No. 726,284.

To all whom it may concern:

Be it known that I, DEMPSEY G. BRITTON, a citizen of the United States residing at Connersville. in the county of Fayette and State of Indiana, have invented certain new and useful Improvements in Radiators, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to radiators for automobiles, tractors, trucks and the like. The primary object of the invention is to provide a water-cooling radiator of the character indicated so constructed that it may be readily assembled r disassembled as occasion may require, so that if repair or replacement of any of the parts become necessary, the radiator may be quickly taken to pieces, the faulty parts restored or new ones substituted therefor. and the radiator reas sembled in a minimum length of time and at a small expense.

It is a further object of the invention to provide a radiator of the character indicated presenting a very large radiating surface and providing for a maximum efficiency of air circulation therethrough.

Further objects and advantages of the in vention will be set forth in the detailed description which follows:

In the accompanying drawings;

Figure 1 is a fragmentary front elevation of a radiator with certain of the parts in section, illustrating the invention.

Fig. 2 is a fragmentary horizontal sectional View on line 2-2 of Fig. 1.

Fig. 3 is a fragmentary transverse, vertical sectional view.

Fig. 4 is a fragmentary perspective view illustrating one of the punched out portions of the spacing and radiating plates, hereinafter described, and

Fig. 5 is a Iragmentaryfront elevation of one of said plates.

Like numerals designate corresponding parts in all of the figures of the drawing.

The radiator of the present invention comprises upper and lower headers 5 and 6. The lower face of the upper header and the upper face of the lower header are substantially alike in construction and such construction is best illustrated in Fig. 3; from which it will be seen that said headers are provided in their confronting faces with circular depressions 7 in which the ends of the relatively thin tubes 8 are received. Suitable packing washers 9 are disposed between ner as to form grooves 13 which receive the upper and lower edges of radiating and spacing plates 14. These plates are cut and struck out, as indicated at 15 in Fig. 5. In

other words these out out portions comprise straight side and semi-circular end portions 15. The portion struck out of said opening is bent at right angles as is indicated at 16 and since the cut at 15 is a semi-circular cut it follows that the ends of the bent por- I v:

tions present semi-circular recesses adapted to snugly receive and partially embrace the adjacent tubes 8. Those plates that are located between rows of tubes have the portions 16 bent in opposite directions at alternate cuts 15, while the front plate 14 which lies in front of the front row of tubes has its cut out portions bent rearwardly only. In like manner the rear plate 14 has its cut out portions bent forwardly, only. The front and rear plates protect the adjacent rows of tubes. The intermediate plates 14; properly embrace and support the rows of tubes and constitute radiating elements to carry off the heat from said rows of tubes. The openings 15 formed by striking out the portions 16 provide passages for the air to circulate freely through the radiating plates 14, 14 and 1 1 and past the rows of tubes. Thus the tubes are cooled and the plates are cooled and the heat is rapidly carried off. Consequently the radiator is highly efficient in use. At the same time it lends itself to ready disassembly for purposes of repair or replacement of any of the parts, it being manifest that it is only necessary to loosen the bolts 11 in order to separate the headers and to remove all of the tubes and the spacing and radiating plates.

As is best illustrated in Fig. 2, the tubes are disposed in staggered relation but the invention is not limited to any specific arrangement of the tubes.

If desired bracing straps 17 may be disposed vertically between the headers 5 and 6 and tie bolts 18 may extend transversely through the adiators and connect said straps. However this feature may be omitted if desired, though it is preferred to employ the same.

It is to be understood that the invention is not limited to the precise construction set forth but that it includes withinits purview Whatever changes fairly come within the terms or the spirit. of the appended claims.

Having described the invention what is claimed is: I

1. A radiator comprising upper and lower headers, means for drawing said headers forcibly toward each other, a plurality of rows of tubes extending across said headers from side to side of the radiator, means for establishing fluid tight joints between said tubes and said headers under the action of said drawing means, plates extending across the radiator from side to side, means carried by the confronting faces of said headers for engaging the upper and lower edges of said plates respectively and cut out elements carried by said plates having semi circular recesses in their ends, said recessed ends bearing against and engaging said tubes, as and for the purposes set forth.

2. A radiator comprising upper andlower headers, means for drawing said headers forcibly toward each other, a plurality of rows of tubes extending across said headers from side to side of the radiator, means for establishing fluid tight joints between said tubes and said headers under the action of said drawing means, plates extending across the radiator from side to side, means carried by the confronting faces of said headers for engaging the upper and lower edges of said plates respectively and cut out elements carried by said plates bent to substantially horizontal planes and projecting in opposite directions from said plates and having their ends engaged with the rows of tubes in the front and rear thereof respectively.

3. A radiator comprising upper and lower headers, means for drawing said headers forcibly toward each other, a plurality of rows of tubes disposed across said headers from side to side of. the radiator, with all of the tubes of a row in substantially the same plane, means for establishing fluid tight joints between said tubes and said headers under the-action of said d'awing means, plates extending across the radiator from side to side and disposed between the rows of tubes, means carried by the confronting faces of said headers for engaging the upper and lower edges of said plates and cut out elements carried by said plates, bent to substantially horizontal planes and engaging the outer surfaces of the tubes of an adjacent row of tubes.

In testimony whereof I hereunto affix my signature.

DEMPSEY C. BRITTON.
